Referring to fig. 1B, fig. 1B is a schematic flowchart of a positioning method provided in an embodiment of the present application, where the method is applied to a monitoring system, the monitoring system includes a plurality of sensing devices, a first server and a second server, and the plurality of sensing devices, the first server and the second server maintain communication connection therebetween, where the first server is specifically a communication proxy server and a second server public security server in the embodiment of the present application, and the plurality of sensing devices are respectively disposed at an exit and an entrance of a train station, and the method includes the contents shown in steps 101 to 106:

step 101: the monitoring system collects information of boarding personnel through sensing equipment at the station entrance of the current station.

The specific implementation process of collecting the information of the boarding personnel can be as follows: shooting images or videos of the boarding personnel through a camera of the sensing equipment, and collecting information of the boarding personnel; or the sensing equipment is arranged at a gateway of the station entrance, and the information of the boarding personnel is acquired through the scanning function of the sensing equipment.

Step 102: and the monitoring system identifies the identity of the boarding personnel based on the information of the boarding personnel.

The identity of the boarding personnel can be identified through the sensing equipment at the station entrance of the current station, the acquired information of the boarding personnel can be uploaded to the first server through the sensing equipment, the identity of the boarding personnel is identified through the first server, and then the identification result is issued to the sensing equipment.

Optionally, when the information of the boarding person is image information, a specific implementation process for identifying the identity of the boarding person based on the information of the boarding person may be as follows: determining a face image of a boarding person in the image information, identifying the face image, and determining a candidate region where a preset key part in the face image is located based on a target detection algorithm, wherein the target detection algorithm can be one of a YOLO algorithm, an SSD algorithm and the like; identifying the image in the candidate region where the preset key part is located, and determining whether a covering object exists in the preset key part; when at least one key part in the preset key parts is determined to have the covering object, identifying the type of the covering object; when the type of the covering object is determined to be a preset type, extracting the features of other key parts except the at least one key part in the preset key parts, acquiring the feature information of each key part in the other key parts, and comparing the feature information of each key part with template information which is stored in a database in advance and corresponds to each key part to obtain the matching degree of each key part; and if the matching degree of at least one key part in each key part is greater than a threshold value, marking the boarding personnel as target personnel.

The template information pre-stored in the database is characteristic information obtained after extracting information of key parts of suspicious personnel.

The implementation process of determining whether the preset key part has the covering object may be: and intercepting the key part image of the candidate region, inputting the key part image into a pre-trained occlusion recognition network, outputting a feature vector of the key part image, and matching the feature vector with a template vector to obtain whether the key part image contains an occlusion and an occlusion type corresponding to the template vector.

Wherein the preset key parts include, but are not limited to, mouth, eyes, nose, and the like.

Wherein the predetermined types include, but are not limited to, sunglasses, masks, beards, hats, and the like.

In a possible example, after determining whether the preset key part has the cloak or not, when identifying the identity of the boarding personnel, the method can also be realized by the following method: determining the key parts of the preset key parts with the shelters, calculating the ratio of the number of the key parts with the shelters relative to the number of the preset key parts, and marking the boarding personnel as target personnel if the ratio is greater than a threshold value, wherein the threshold value can be 70%, 80% or other values.

In a possible example, after determining whether the preset critical position has the cloak or not, when identifying the identity of the boarding personnel, the method can also be realized by the following method: determining the covering area of the covering in the face image and the total area of the face image, and calculating the ratio of the covering area to the total area of the face image, if the ratio is greater than a threshold value, marking the boarding person as the target person, wherein the threshold value can be 40%, 50% or other values.

In a possible example, if the boarding person goes back to the sensing device or goes low head to the vehicle, the facial image of the boarding person cannot be acquired, so that the identification of the identity of the boarding person based on the facial image cannot be realized at this time, and for the boarding person, the head and shoulder images of the boarding person are generally acquired, so that in order to solve the problem that the facial image cannot be acquired, another specific implementation process for identifying the identity of the boarding person is provided as follows: preprocessing the image information to obtain a target image with a preset size (namely the size matched with the network model), inputting the target image into a pre-trained head and shoulder recognition network, and determining a head and shoulder area in the target image based on a YoLo algorithm pre-embedded in the head and shoulder recognition network; extracting a feature vector of a head-shoulder image in the head-shoulder region; comparing the feature vector of the head and shoulder image with the template vectors in the template library to obtain the matching degree, and if the matching degree is greater than a threshold value, determining the boarding personnel as the target personnel; and the template vectors in the template library are the characteristic vectors of the head and the shoulder of the target person.

The above mentioned extraction of feature vectors is all extracted by a convolution network model, and the extraction of feature vectors by the convolution network model is the prior art and will not be described.

Step 103: when the target person is contained in the boarding personnel, the monitoring system acquires a train schedule through the first server, and determines the next stop of the train based on the train schedule and the current stop.

Optionally, the acquiring, by the monitoring system through the first server, the train schedule specifically includes: : the first server acquires train number information of the train, and inquires a train schedule corresponding to the train number information in a database based on the train number information, namely the train schedule is acquired.

Further, after the train schedule of the train is obtained and the current station determines the stop time and stop (i.e., stop location) of the next station of the train, so that the first server notifies the sensing device of the next stop to start the working mode in the pre-stored mapping relationship between the sensing device and the stop location, so as to collect the information of the person getting off at the next stop.

Step 104: and the monitoring system acquires the information of the personnel getting off the bus through the sensing equipment at the exit of the next stop station.

The information of the person getting off the bus is collected to be consistent with the information of the person getting on the bus, and description is omitted.

Step 105: and the monitoring system identifies the identity of the person getting off the vehicle based on the information of the person getting off the vehicle.

The identity of the person who gets off the vehicle is identified to be consistent with the identity of the person who gets on the vehicle, and description is omitted.

Step 106: when the target person is contained in the get-off person, the monitoring system positions the target person in the get-off person through the second server.

Optionally, the implementation process of the monitoring system locating the target person in the getting-off person through the second server may be: when the sensing device of the next stop station exit determines that the getting-off personnel comprises the target personnel, the characteristic information of the target personnel is obtained and reported to a first server (a communication proxy server), the characteristic information of the target personnel is reported to the first server, the first server sends a positioning instruction to a second server, the positioning instruction comprises the characteristic information of the target personnel, and the second server positions the target personnel based on the positioning instruction.

It can be seen that, in the embodiment of the application, whether a target person is mixed in a train is determined through a monitoring system, whether the target person is mixed in a person getting on or off the train is determined through a face recognition strategy or a head and shoulder recognition strategy, the accuracy of target person recognition is improved, when the target person is mixed in, the getting on or off place of the target person is monitored, and the getting off place is forwarded to a public security server, so that the accurate monitoring of the target person mixed in the train is realized, the security measures of a railway station are favorably improved, the public interest is protected, and data support is provided for the capture and the arrangement control of a public security department.

In a possible example, the method further comprises: when the feature information of the target person is obtained, obtaining a target image containing the target person through sensing equipment at the exit of the next stop station, and performing feature extraction on the target image to obtain the feature information of the target person; acquiring the position information of the target personnel through the sensing equipment at the exit of the next stop station, namely acquiring the position information of the target personnel through a GPS (global positioning system) module in the sensing equipment); and sending the characteristic information and the position information of the target person to a first server so that a second server can position the target person according to the characteristic information and the position information of the target person.

In the above possible example, when the sensing device of the exit of the next stop is a sensing device that is arranged at an exit from an underground parking lot, that is, when there is no GPS signal area and the position information of the target person cannot be obtained based on the GPS positioning module, the process of obtaining the position information of the target person by the sensing device of the exit of the next stop may be: acquiring a first target image containing target personnel through sensing equipment of the underground parking lot; the method comprises the steps of obtaining a marker in a first target image, determining a motion track of a target person in the underground parking lot based on a pre-stored scene distribution map of the underground parking lot and the marker, determining an exit of the target person in the underground parking lot based on the motion track, and taking position information of the exit as position information of the target person.

Wherein, acquiring the marker in the first target image specifically comprises: extracting a background area in the first target image, identifying a background image in the background area, and determining a marker in the background image.

It can be seen that, in this example, through the perception device of the underground parking lot, the positioning scene of the perception device is widened, and the position of the target person who escapes to the underground parking lot can be positioned, so that the problem that positioning cannot be performed due to lack of a GPS signal in the underground parking lot is solved.

In one possible example, when the current station is an originating station of a train, the method further comprises:

and when determining that the boarding personnel at the current station do not contain the target personnel, the monitoring system controls the sensing equipment at the exit of the next stop to be in a standby state and controls the sensing equipment at the entrance of the next stop to acquire the information of the boarding personnel at the next stop.

In one possible example, upon detection of a target person among boarding persons at an entrance of an origin station, a first number of target persons among boarding persons is detected at an entrance of a first stop station, such as at an entrance of a first stop station

In a possible example, the method further comprises:

when the station stops at the ith station, counting the residual quantity of target personnel corresponding to each station before the ith station and the quantity of the target personnel in the train entering personnel at the station entering port of the ith station to obtain the total residual quantity of the target personnel on the train when the station stops at the ith station, if the total residual quantity of the target personnel on the train is equal to 0, controlling the sensing equipment at the station exiting port of the ith station to be in a standby state, and if the total residual quantity of the target personnel on the train is not equal to 0, controlling the sensing equipment at the station exiting port of the ith station to be in a working state; the step of counting the remaining amount of the target person corresponding to each station before the ith station specifically comprises the following steps: counting a second number K1 of the persons getting on the station at the station entrance of the (j-1) th station and a second number K2 of the persons getting off the station at the station exit of the jth station, and taking (K1-K2) as the residual amount of the target persons corresponding to the jth station; j is more than or equal to 1 and is less than i, the jth station is any one of all stations before the ith station, the ith station is any one of all stop stations of the train, and when j is equal to 1, the residual quantity of target personnel corresponding to the jth station is specified to be zero.

It can be seen that, in this example, the sensing device at the stop exit is judged whether to need to be started or not by detecting the remaining amount of the target person on the train, and when no target person exists on the train, the sensing device at the stop exit does not need to be started, so that the working pressure of the sensing device is reduced, the invalid image information of the person getting off at the moment does not need to be collected, the invalid data processing is avoided, and the working efficiency of the sensing device is improved.

Referring to fig. 2, fig. 2 is another positioning method provided in the embodiment of the present application, where the positioning method is applied to a sensing device, where the sensing device includes a sensing device disposed at an entry port and a sensing device disposed at an exit port, and the method includes the following steps:

Step 202: and the sensing equipment identifies the identity of the boarding personnel based on the information of the boarding personnel.

Step 203: and when determining that the boarding personnel comprise the target personnel, the sensing equipment reports a monitoring instruction to the first server.

Step 204: and the sensing equipment acquires the information of the personnel getting off the bus at the exit of the next stop station.

Step 205: the sensing equipment identifies the identity of the person getting off the vehicle based on the information of the person getting off the vehicle.

Step 206: when the situation that the target person is contained in the getting-off person is determined, the sensing equipment reports a positioning instruction to the first server, and the positioning instruction is forwarded to the second server through the first server.

The positioning instruction is used for indicating the second server to position a target person in the getting-off persons based on the positioning instruction, and the positioning instruction comprises characteristic information of the target person.

It can be seen that, in the embodiment of the application, whether a target person is mixed in a train is determined through the sensing device, whether the target person is mixed in a person getting on or off the train is determined through the face recognition strategy or the head and shoulder recognition strategy, the accuracy of target person recognition is improved, when the target person is mixed in, the getting on or off place of the target person is monitored, and the getting off place is forwarded to the public security server, so that the accurate monitoring of the target person mixed in the train is realized, the security measures of a railway station are favorably improved, the public interest is protected, and data support is provided for the capture and the arrangement control of a public security department.

Step 302: the first sensing equipment determines the identity of the boarding personnel based on the information of the boarding personnel.

Step 303: when the target person is determined to be included in the boarding person, the first sensing equipment reports a monitoring instruction to the communication proxy server.

The monitoring indication is used for indicating the first server to acquire a train schedule, and determining the next stop of the train based on the train schedule and the current stop; and the sensing equipment used for indicating the next stop is started to work when the train stops at the next stop.

Step 304: and the communication proxy server acquires a train schedule based on the monitoring indication and determines the next stop of the train based on the train schedule and the current stop.

Step 305: and when the train stops at the next stop, the communication proxy server instructs the second sensing equipment to start the working mode.

Wherein the second sensing device is the sensing device of the next docking station.

Step 306: and the second sensing equipment acquires the information of the personnel getting off at the exit of the next stop station.

Step 307: the second sensing device identifies the identity of the person getting off the vehicle based on the information of the person getting off the vehicle.
